CEOS-WGCV ACIX II - CMIX:
ACIX and CMIX are international collaborative initiatives to inter-compare a set of atmospheric correction (AC) and cloud masking (CM) algorithms for high-spatial resolution optical sensors. The exercises will focus on Sentinel-2 and Landsat-8 data over a set of test areas. The inter-comparison of the derived cloud masks is expected to contribute to a better understanding of strengths and weaknesses of different algorithms and ultimately to contribute to a reduction of a major error source for atmospheric correction and surface parameter retrievals. Similarly, the study of Bottom-of-Atmosphere (BOA) products will assist in understanding the different uncertainty contributors and improving the AC processors.
Objectives and Expected Outcomes
The exercises brought together the developers of CM and AC algorithms and related software processors. The corresponding protocols were defined together by coordinators and participants and it was mandatory to be followed by all the participants of the exercises. The input data are Landsat-8, Sentinel-2A and -2B products of various test sites, covering various land cover types, i.e. agricultural, coastal, snow, water, deserts etc. The participants generate the corresponding CM and AC products, which are validated following the corresponding protocols.
